Windows
To open and close a window
Ignition key in position 1 or higher:
>Press the switch downward until you feel
resistance: the window continues to move
downward as long as you continue to press
the switch
>Tap the switch past the pressure point:
the window moves downward automati-
cally. Tapping the switch again stops the
opening cycle.
You can close the window in the same manner
by pulling the switch upward.
If you wish, you can have this special fea-
ture activated/deactivated.<
After the ignition has been switched off
You can still open or close the windows for up to
15 minutes, as long as no one opens any of the
doors.
When leaving the vehicle, always remove
the ignition key from the lock and remem-
ber to close the doors, since children could oth-
erwise operate the windows and injure them-
selves, etc.<
For convenience operation via the remote con-
trol or the door lock, refer to page17 or18,
respectively.
Pressure-sensitive finger guard
system
If the closing force exceeds a certain value while
a window is being raised, the system will
respond by stopping the window and then
retracting it a small distance.Despite the finger guard system, make
sure that the windows can close without
obstruction, since in some cases, e.g. with thin
objects, it is not guaranteed that the closing
operation will be interrupted.
The finger guard system function is restricted
when the switch is pulled and held beyond the
pressure point.<
After a power supply interruption
After a power supply interruption, for instance
after disconnecting the battery, the pressure-
sensitive finger guard system must be reinitial-
ized:
Ensure that the doors and convertible top are
closed before initializing. Perform the following
procedure twice for each window:
>Open and close the window completely
>With the window closed, keep pulling the
switch upward for approx. 1 second.
Manual convertible top
The fabric top offers perfect protection against
the weather and it can be opened easily and
quickly by one person alone.
Here are a few tips so that you get the most out
of your BMW:
>It is advisable to close the convertible top
when the vehicle is parked. The closed con-
vertible top not only protects the passenger
compartment from unforeseeable damage
from the weather, but also provides a cer-
tain degree of theft protection
>In addition, only keep valuables in the
locked luggage compartment, even with the
convertible top closed
>When the convertible top is open, the cen-
tral locking system also locks the release
button for the convertible top. The convert-
ible top cannot be operated. This provides
better theft protection for valuables stored
in the luggage compartment
>Never mount a roof-mounted luggage rack
system on the convertible top.

Opening and closing
22 the top not only guards the passenger com-
partment from unforeseeable damage from
the weather, but also affords a degree of
protection against theft. In addition, only
keep valuables in the locked luggage com-
partment, even with the convertible top
closed
>Never mount a roof-mounted luggage rack
system on the convertible top
>To avoid damage, do not operate the con-
vertible top at temperatures below 147/
–106.
To avoid permanent damage from mois-
ture, never store the convertible top while
it is wet.
Driving when the opening or closing process
has not been completed can cause vehicle
damage or personal injury.
Do not lay objects on the convertible top, since
they could fall off when the convertible top is
operated and cause damage or injuries.
Do not reach into the convertible top mecha-
nism during opening and closing. Keep children
away from the moving parts of the convertible
top during operation.<
If possible, only operate the convertible
top with the vehicle stopped, as other-
wise the process may be interrupted.
If you set the convertible top in motion while the
vehicle is stationary and then have to start sud-
denly, for instance at a traffic light, you can still
complete the procedure by driving as slowly as
possible and again holding the corresponding
button pressed.
At higher speeds, a vacuum effect in the pas-
senger compartment can cause the convertible
top to begin fluttering. Increase the air supply
so that a low pressure draft does not occur in
the vehicle.<

2To open
If at all possible, only operate the convert-
ible top if the engine is running. This
saves unnecessary battery wear.
Before closing the convertible top, remove any
objects from the windshield frame that could
keep the convertible top from closing prop-
erly.<
Ignition key in position 1 or higher.
With the vehicle standing.

pressing the button while doing so until the top
starts up again on its own.

light up while the convertible top is in
motion. It goes out as soon as the opening
or closing operation has been completed

flashes after the button has been released,

Maintenance
The BMW Maintenance
System
The BMW Maintenance System helps maintain
the road safety and operating reliability of your
BMW.
Please keep in mind that regular maintenance is
not only necessary for the safety of your vehi-
cle, but also plays a significant role in maintain-
ing the resale value of your vehicle.
Service interval display
While conventional systems rely on distance
traveled alone to determine when a service is
due, the BMW Maintenance System has taken
the actual conditions under which the vehicle is
operated into consideration for years, because
miles can be traveled in many different ways:
From a maintenance point of view,
60,000 miles/100,000 km accumulated in
short-distance urban driving are not the same
as 60,000 miles/100,000 km accumulated at
moderate cruising speeds in long-distance
highway travel.
The BMW Maintenance System includes the
Engine Oil Service and Inspections I and II.
Determining the maintenance intervals based
on the actual loads on the vehicle covers every
kind of operating situation. Minimal use drivers,
who drive fewer than about 6,200 miles/
10,000 km per year, should nevertheless have
the oil changed at least every 2 years since
engine oil deteriorates over time, regardless of
use.

Service Guide Booklet for Canadian
models
For additional information on required mainte-
nance intervals and procedures, please refer to
the Service and Warranty Information Booklet
for US models, or the Warranty and Service
Guide Booklet for Canadian models.
Depending on operating conditions, it may be
advisable to have the body checked for damage
from rocks or gravel as a precaution against cor-
rosion.
BMW recommends that you have your
BMW center perform the maintenance
and repair.
Be sure that all maintenance work is recorded in
the Service and Warranty Information Booklet
for US models, Warranty and Service Guide
Booklet for Canadian models. These entries will
serve as proof that the vehicle has received reg-
ular maintenance.<
